Overall distribution of age at parturition for the Palanan Agta. The overall distribution of the age at parturition in the Agta is obtained by averaging the age distributions obtained by the procedure depicted in Fig. 5 for all pairs of mother and child in our Palanan Agta dataset (blue density). This overall age distribution excludes 23 pairs for which the ages of both the mother and child are precisely known, which are shown separately (histogram).
